Attacks on this boat and other events

16 Sep 19421935hrs, NE of the Faeroe Islands: the boat was located by a Whitley aircraft (612 Sqn RAF/R) on A/S sweep which used cloud cover in an attempt to surprise U-620, but she was already submerging as six 260lb depth charges were dropped ahead of the bows. No damage. (Sources: KTB U-620/ADM 199-1783)

24 Oct 1942An unidentified land-based aircraft attacked and seriously damaged the boat while she was hunting convoy ON-139. The boat abandoned the attack and moved to a new area. (Sources: Blair, vol 2, page 43.)

10 Nov 19421430hrs, 15 miles NNW of El Ferrol, Spain, inbound: boat was attacked by a British Whitley (502 Sqn RAF/G). The aircraft made a sharp turn to starboard to evade AA fire from the U-boat during the first approach and then turned again to attack from less than half a mile with the front gunner returning fire. The AA gunners had not anticipated this maneouver, and as they had opened fire too early their clips were empty as the Whitley attacked from the starboard beam and dropped six depth charges about 100ft (30m) ahead of the boat. The explosions were too far away to cause damage, but machine gun fire from the rear gunner mortally wounded one man [Bootsmaat Josef Leisten]. U-620 escaped further attacks by crash diving immediately afterwards. (Sources: KTB U-620, ADM 199/1783)
